Tool carrier

Abstract

The invention pertains to a fiber-reinforced rotationally symmetrical tool carrier, a corresponding manufacturing method and a grinding tool. The tool carrier can be separably connected to a rotary drive and contains a tool receptacle surface for receiving a grinding, rough-grinding and/or polishing element. The tool carrier and the grinding tool contain a fiber reinforcement that consists at least partially of natural fibers.

What is claimed:  
     
       1. A rotationally symmetrical tool carrier which can be separably connected to a rotary drive, with a tool receptacle surface for receiving at least one grinding and/or polishing element, with a fiber reinforcement that comprises at least partially of natural fibers, and with a binder for stabilizing the natural fibers, wherein the binder consists of one of the materials polyurethane, polypropylene, phenol resin, epoxy resin or biological polymer. 
     
     
       2. The tool carrier according to  claim 1 , wherein the binder comprises of lignin. 
     
     
       3. The tool carrier according to  claim 1 , wherein the binder is based on corn starch. 
     
     
       4. The blank for being additionally processed into a tool carrier, a tool, a woven fabric carrier or a woven fabric according to  claim 1 , wherein the blank is manufactured from a fiber mat that comprises at least partially of natural fibers and contains a binder for the natural fibers. 
     
     
       5. The blank according to  claim 4 , wherein the blank is manufactured from at least two fiber mats that comprises at least partially of natural fibers and contain a binder for the natural fibers, and by the fact that the fiber mats are placed on top of one another in a sandwich-like fashion and bonded to one another. 
     
     
       6. The blank according to  claim 4 , wherein abrasive grain is applied onto the surfaces of the fiber mats before the bonding process. 
     
     
       7. A method for manufacturing a tool carrier, a woven fabric carrier, a woven fabric, a grinding or polishing tool or a blank according to  claim 1 , wherein a pulp is produced from natural fibers and a binder, plate-shaped basic elements are produced from the pulp, the basic elements are compressed and shaped by means of a pressing tool in such a way that several blanks are produced adjacent to one another, and the blanks are subsequently punched out. 
     
     
       8. The method according to  claim 7 , wherein the abrasive grain is added to and homogeneously distributed in the pulp such that the abrasive grain is uniformly distributed in the objects manufactured therefrom. 
     
     
       9. The method for manufacturing a tool carrier, a woven fabric carrier, a woven fabric, a grinding or polishing tool or a blank according to  claim 1 , wherein a pulp is produced from natural fibers, by the fact that mat-like basic elements are produced from the pulp, by the fact that the basic elements are sprayed with a binder, by the fact that the basic elements are compressed and shaped into a blank by means of a pressing tool, and by the fact that the blank is punched out. 
     
     
       10. The method for manufacturing a tool carrier, a grinding or polishing tool or a blank according to  claim 9 , wherein several layers are, after being sprayed, bonded together in a sandwich-like fashion such that a basic element is formed. 
     
     
       11. The method for manufacturing a tool carrier, a grinding or polishing tool or a blank according to  claim 9 , wherein the spraying is carried out with a binder that is heated to a temperature between 100 and 200° C., preferably 150° C. 
     
     
       12. The method for manufacturing a tool carrier, a grinding or polishing tool or a blank according to  claim 9 , wherein the compressing process takes place at room temperature. 
     
     
       13. The method for manufacturing a tool carrier, a grinding or polishing tool or a blank according to  claim 9 , wherein the blank is hardened for one to two days. 
     
     
       14. The method for manufacturing a tool carrier, a grinding or polishing tool or a blank according to  claim 9 , wherein the fiber mat has a weight of approximately 1100-1500 g/m 2  and a thickness of approximately 2.5-4 mm in the compressed state. 
     
     
       15. The method for manufacturing a tool carrier, a grinding or polishing tool or a blank according to  claim 9 , wherein the mat-like basic elements are subjected to a needling process before being sprayed. 
     
     
       16. The method for manufacturing a tool carrier, a grinding or polishing tool or a blank according to  claim 9 , wherein the compressing process is carried out with a pressure between 15 and 35 bar. 
     
     
       17. The method for manufacturing a tool carrier, a grinding or polishing tool or a blank according to  claim 16 , wherein the compressing process takes place at a temperature between 100 and 200° C. 
     
     
       18. A woven fabric carrier for woven grinding and polishing fabrics, comprising a woven fabric carrier manufactured at least partially from natural fibers. 
     
     
       19. The woven fabric carrier according to  claim 18 , wherein the binder comprises of lignin. 
     
     
       20. The woven fabric carrier according to  claim 18 , wherein the binder is based on corn starch.
